Patented Dec. 20, 1949 enliven STAT s s PATENT c tric The inventiondescribed "herein may be manu- -factured and used 'byor for theGovernment for governmental purposes without the payment to meet anyroyalty thereon.

- 'My invention refers to improvements in machine 'gun 'mountswhich willcombine the advantages of mobility, rigidity'and safety.

An important object of the invention is to provide a metal wheeledmachine gun mount "which'can be moved quickly from 'one position toanother, and which can then be placed in immediate operation.

Another object of the invention is to provide a metal wheeled machinegun mount which will furnish rigid and stable support to the gun whenoperating.

A furtherobject of the invention is to provide a metal machine gun mountwhich will furnish some degree of protection to the operators of themachine'gun.

Other objects and advantages of the invention will become apparentduring the course of the following description.

The following drawings, forming part of the specification, illustratethe manner in which I attain these objects. Similar numbers are used todesignate like parts throughout the same.

Figure 1 is a plan view of a machine gun mount embodying my inventionwith a machine gun Figure 2 is a rear elevation of the same, and

Figure 4 is a perspective view of the hinged body or mounting unit.

In the drawings the numeral 4 designates a tubular body, preferablycircular in cross-section, having a circumferential flange Ad on thetop, and terminating in a conical end b. The tubular body 4 is providedwith diametrically disposed wings 5 having a plurality of holestherethrough for pivotally attaching the said body to a pair of steelcross pieces 6, each said cross piece having one bifurcated end forminga clevis having a plurality of registering holes in the opposed wallsthereof to receive and engage said wings 5 therein by means of a fixedswivel pin 1 and for the insertion of a loose pin 8 attached to thesteel cross pieces by a chain. When this loose pin is removed thetubular body will drop automatically and the conical end will enter theground. The loose pin may then be inserted in other registering holesprovided therefor and will hold the unit in its new position.

The steel cross pieces are bent at the end and arranged to receive theaxle 9 which is attached thereto by a fixed swivel pin it and by a loose2 pin llattached to the cros pieces by-a chain. When the loose pin isremoved the solid metal wheels l2 may be swung laterally to provideprotection-"for the operators of the machine gun and alsoadd to theri'gidity of the mount. Braces '23 to which trail shoes M are rigidlattached, are attached to "the steel cross pieces by ball joints [5, andacross brace l6 provided to separate the said braces when the gun is inopera-tidn. l v V I v c The operation of the machine gun mount is asfollows: When the mount "bearing a machine gun has been brought into itsposition and loose position, the conical {end entering the ground B'areremoved, the tubular body will pivot on the fixed swivel pins 1 and dropto its lower ts fix the ground position or the mount. The lo'ose pinsare then inserted in the holes provided in {the wings 5 and the mount isfixed rigidly initsfnewposition. When the loose pin H is removed, thesoli'dfmetal wheel 12 and its "axle '9 is swung forward, pivoting on thefixed swivel pin ll! an'd is held in its new place,

furnishing bothrigidity to the mount and a olegree of protection from"cross fire to the gun operators, when the loose pins H are-inserted inthe holes provided in the'axle Q'for this purpose.

The braces t? which have'been'folded'in a Carryin'g'iiOsitio'n againstthe mount retained in said position by means of removable straps 6r"ties [3a while the gun'was being moved may *be "dropped to furnish backbracing for the mount, and are held rigidly in position by means of thecross brace I6.

It is to be understood that the form of my invention herewith shown anddescribed, is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to, without departing from the spirit of my invention, or thescope of the subjoined claims.

Having thus described my invention, 1 claim:

1. A mount for machine guns comprising a tubular body portion flanged atthe top and with a conical end, side flanges formed integral with saidbody, said flanges being provided with openings therein, steel crossbeams pivotally connected at one end to said flanges, means for loweringand raising of the mount, stub axles pivoted to the other end of saidcross beams and each arranged to swing about a Vertical axis, metalwheels on said axis responsive to the swinging movement thereof toassume a first position for moving the mount forward and a secondposition wherein said mount is lowered and said wheels are dis:-

posed at an acute angle to a vertical plane through the center of andtoward the top of said mount, and at an acute angle to a horizontalplane through the center of and forward of said mount in which positionsaid wheels are adapted to form a shield for the operators, cooperatingmeans carried jointly by said cross beams and said axles, includingpin-engaging registering opening in said cross beams and said axles, toselectively secure said cross beams and said axles in said first andsecond positions relative to each other.

2. A machine gun mount comprising a vertically disposed hollow bodyportion having a dependent ground engaging conical portion and acircumferential flange its upper end constructed and arranged to supporta gun, rigid wings formed integral with said body portion on each sidethereof, the said wings having a plurality of openings therein, a pairof steel cross pieces arranged at one end to engage said wings and atthe other end to engage an axle, a pair of stub axles, each said axlebeing arranged at one end to engage a wheel, and having a pair ofaligned openings 00- axial with said axle at the other end, pivot meanstherethrough, a pair of cross members, each said cross member having aclevis formed at one end to engage one of said wings for pivotalmounting therein, the opposed side walls of each said clevis having anopening arranged to register with one of the openings in a said wing toreceive a removable pin cooperatively connecting said wings and crosspieces when the said cross pieces are aligned in a substantiallyhorizontal first position and with another of said wing openings forsimilar pin connection of said wings and cross pieces when the saidcylindrical member is translated downward and the said cross pieces aredisposed downwardly and inwardly relative to the at each end of eachsaid cross piece for pivotal r1 connection of a respective said wing andsaid axle therewith, removable pin means engaging said cross pieces andsaid wings to maintain said cross pieces in a substantially horizontalfirst position and for locking said cross pieces in a second downwardand inwardly disposed position when the said body portion is translateddownwardly on its pivotal connections, there being openings in saidcross pieces arranged to register with openings in said wings when saidbody is in said first and second positions respectively, a secondremovable pin means engaging said cross pieces and said axles tomaintain said axles in a plurality of adjusted positions relative tosaid cross pieces, there being openings in the adjacent end of each saidcross piece arranged to register with one of the openings in said axlewhen said axle is swung on its pivot to such adjusted positions.

3. A machine gun mount comprising a vertically disposed hollowcylindrical member, the

dependent end of said member being tapered to form a ground engagingportion, the other end of said member being provided with an externalcircumscribing flange adapted to support a gun, a pair of diametricallydisposed wings formed integral with said cylindrical member, each saidwing being provided with a plurality of openings horizontal, the otherends of said cross pieces being flattened and provided with a pluralityof openings therethrough, stub axles pivotally mounted on the respectiveflattened ends of said cross members for transverse swinging movement ofsaid axles relative to said cross members about a normally verticalaxis, the said stub axles having means on the ends opposite said pivotalconnections to mount; a wheel, each said axle having an openingintermediate said pivotal connection and said wheel mounting meansarranged to register with one of the openings in said flattened portionto receive a removable pin for cooperatively connecting said flattenedportion and said axle when said cross members are in a substantiallyhorizontal first position and with another said opening in saidflattened portion when said axle is swung transversely relative to saidportion.
